The brain never lazy

What to do when you do not want anything?

I do not just do not want to, but really, really do not want to?

Are you familiar with this condition?

Some people are in it all the time, but contrary to what he thinks about them that part of humanity that wants a few more of their brain is not idle. No no! It can be so loaded that it is not enough forces on the action.

This idea was proposed by scientists from the British University of Oxford, who looked at the brain lazy and passive people using functional magnetic resonance imaging, asking at the same test to decide on one of the proposed action: one was more complicated, and the second - at least.

No surprise that most people chose the second type of activity. But, to the amazement of the scientists, not because the brain experiment participants were less active. On the contrary: it was seething with activity, especially in the premotor regions of the cortex, where future actions are planned.

When making decisions, the activity of this brain region was much higher in people apathetic than the energetic. She was so great that the process of decision-making seemed to absorb all the energy that was lacking after the translation of intentions into action.

It seems that people with low motivation (well, maybe not all), there are some with "cogs" of the problem in the brain. Areas responsible for decision-making, they work efficiently, spending nearly one fifth of the energy required for the brain.

Therefore, for their gray cells to take action - it's an incredible effort. Perhaps this discovery will allow finding more effective therapies for people suffering from depression or apathy, preventing normal operation.

First of all, this opening partly relieve us of the blame for our own weaknesses. However, by the beginning of the year we still have a couple of news for you.

Something for being late

Scientists have made a discovery that may allow always late to feel a little better. The problem is very serious: it is estimated that in the United States alone every year of delay cause damage to the economy 90 billion dollars.

Who usually late?

Psychologists say that it is, for the most part, people with behavioral type Q. Who is that?

In principle, they are best described by comparison with holders of Type A behavior, who live in a constant state of stress under the pressure of haste, often prone to rivalry and ambition, hostile to others, they see in the surrounding threats.

Holders of behavioral type in such features do not possess. It is good for them: no matter what kind of work they do, and 70 years, they rarely threatened heart attack, although their ambitions they also have.

At the same time they are more prone to the multitasking, higher value on relationships with people than goals, and another - often late. Behavioral type is less dependent on education, and more - from the inherited traits of temperament, so, according to researchers from the American University in San Diego, the habit of late - is in our blood, and it is difficult to eradicate (this, of course, not means that it absolutely hopeless!).

It calms? In the context of all those New Year's resolutions, which we never fails, it is!

Something for dormice

Then one more thing: if you decide in the new year a good sleep, we have to talk you out of it. It turns out that an excessive amount of sleep leads to the same disastrous consequences as the lack of it. It causes havoc in the body, which leads to metabolic disturbances, diabetes and even cancer!

In the short term, long sleep reduces the mood, and, surprisingly, a feeling of fatigue. You know it's reminiscent of a hangover state when in the day you finally managed to sleep until noon?

Our brain, as shown by the long-term study called The Harvard Nurses Study, can not handle it. Why? Because stray biological clock. And they work like the sun, and control the various physiological processes of the body.

Approximately 4.30 person pressure reaches the lowest level of per day, about 19 hours reaches a maximum temperature of the body, and about 21 hours of sleep begins to stand melatonin hormone, due to which we are beginning to droop eye.

These biological clock controls the sunlight, but they are in the nucleus of the anterior region of the hypothalamus. They are subject to all other so-called peripheral, clocks in our body that are in various tissues and organs.

The rhythm of change of light and darkness, which synchronizes all the clocks can be broken (in the winter or during transcontinental flights). What happens then? All watches in our body begin to work at their own pace.

Hormones liver does not stand out during lunch, melatonin will tend to have to sleep during the important conference, and the stress hormone cortisol, the largest concentration of which is usually observed at about 7 am, will not allow us to sleep after a busy day.

The effect of this cacophony becomes known traveling in the other hemisphere desinhroniya. The same symptoms we experience when we try to compensate for the lack of sleep the weekend for a working week. It is better to sleep a little longer, but only a little.

Scientists say that the ideal - eight hours. Fewer and larger amount of sleep is not going to benefit us.

In addition, if a long stay in bed, our brains can change the level of various hormones and neurotransmitters, and in the end we rashochetsya want something.
